Most of what you're complaining about in Wonders of Life were due to Disney negligence, not guest attendance. Let me just say that each of the times I've been to Epcot, not only did I happily go through everything in that pavilion, but the lines there were just as long as any of the others I encountered, except perhaps Test Track...and to me that is really a sad statement. I think part of what might have been needed was to make the Wonders of Life more visible from the main walkways. It always seemed to me it was set back too far behind a lot of greenery, and if it weren't for the giant DNA, and one or two small signs, you could easily bypass it. That's a shame for those who missed it, because it had some wonderful (and yes, educational - that now evil concept) stuff in it. Cranium Command and "The Making of Me" are on my list of all-time Imagineering greats. I'm just happy I have videos of all of the attractions in there to remind me of the way EPCOT once was...amazing.
Now I fear for Spaceship Earth.
